If the mobile carrier cannot be operated or is operated by mistake, the light person will damage the mobile carrier, and the heavy person will also endanger the life safety of the personnel.

Aberration-related variable

Optical Distortion (Optical Distortion) of an Optical imaging system is expressed in ODT; its TV distortion (TVDistortion) is expressed in TDT and can further define the degree of aberration shift described between 50% and 100% imaging field of view; the spherical aberration offset is expressed as DFS; the coma aberration offset is denoted DFC.

The profile curve length of any surface of a single lens in the maximum effective radius range affects the ability of the surface to correct aberrations and optical path differences between the light beams of each field, and the longer the profile curve length, the higher the aberration correction ability, but at the same time, the manufacturing difficulty is increased, so that the profile curve length of any surface of a single lens in the maximum effective radius range must be controlled, and particularly, the proportional relationship (ARS/TP) between the profile curve length (ARS) of the surface in the maximum effective radius range and the Thickness (TP) of the lens on the optical axis to which the surface belongs must be controlled. For example, the length of the profile curve of the maximum effective radius of the object-side surface of the first lens is represented by ARS11, the thickness of the first lens on the optical axis is TP1, the ratio of the two is ARS11/TP1, the length of the profile curve of the maximum effective radius of the image-side surface of the first lens is represented by ARS12, and the ratio of the length of the profile curve of the maximum effective radius of the image-side surface of the first lens to TP1 is ARS12/TP 1. The length of the profile curve of the maximum effective radius of the object-side surface of the second lens is represented by ARS21, the thickness of the second lens on the optical axis is TP2, the ratio of the two is ARS21/TP2, the length of the profile curve of the maximum effective radius of the image-side surface of the second lens is represented by ARS22, and the ratio of the length of the profile curve of the maximum effective radius of the image-side surface of the second lens to TP2 is ARS22/TP 2. The relationship between the length of the profile curve of the maximum effective radius of any surface of the rest of the lenses in the optical imaging system and the Thickness (TP) of the lens on the optical axis to which the surface belongs is expressed in the same way.

The profile length of any surface of the single lens in the 1/2 entrance pupil diameter (HEP) height range particularly affects the ability of the surface to correct aberrations in the shared region of each field of view and the optical path difference between the light beams of each field of view, and the longer the profile length, the greater the ability to correct aberrations, while also increasing manufacturing difficulties, so that the profile length of any surface of the single lens in the 1/2 entrance pupil diameter (HEP) height range, particularly the ratio (ARE/TP) between the profile length (ARE) of the surface in the 1/2 entrance pupil diameter (HEP) height range and the Thickness (TP) of the lens on the optical axis to which the surface belongs, must be controlled. For example, the length of the profile curve of the 1/2 entrance pupil diameter (HEP) height of the object-side surface of the first lens is ARE11, the thickness of the first lens on the optical axis is TP1, the ratio of the two is ARE11/TP1, the length of the profile curve of the 1/2 entrance pupil diameter (HEP) height of the image-side surface of the first lens is ARE12, and the ratio of the length of the profile curve to the TP1 is ARE12/TP 1. The length of the profile curve of the 1/2 entrance pupil diameter (HEP) height of the object-side surface of the second lens is represented by ARE21, the thickness of the second lens on the optical axis is TP2, the ratio of the two is ARE21/TP2, the length of the profile curve of the 1/2 entrance pupil diameter (HEP) height of the image-side surface of the second lens is represented by ARE22, and the ratio of the length of the profile curve to TP2 is ARE 22/TP 2. The relationship between the length of the profile curve of 1/2 entrance pupil diameter (HEP) height of any surface of the remaining lenses in the optical imaging system and the Thickness (TP) of the lens on the optical axis to which that surface belongs is expressed by analogy.

By means of the mobile carrier auxiliary system, the physiological state of the driver can be measured, corresponding detection signals are generated to the warning device, and the warning device can generate corresponding warning signals according to the detection signals for subsequent use and processing, so that driving safety is further improved. For example, the warning device generates warning information when receiving the detection signal of physiological abnormality.

The present invention is not limited thereto. Besides, the vehicle is not limited to a vehicle, and the vehicle may refer to other kinds of vehicles, for example: land trains, aircraft, water vessels, and the like.

The electronic rearview mirror 0100 for vehicle is assembled in a housing 0110, and the housing 0110 has an opening (not shown). Specifically, the opening of the casing 0110 overlaps the reflective layer 0190 of the electronic rearview mirror 0100 for vehicle (fig. 1D), so that the external light can be transmitted to the reflective layer 0190 located inside the casing 0110 after passing through the opening, and the electronic rearview mirror 0100 for vehicle functions as a mirror. When the driver of the vehicle is driving, the driver faces the opening, for example, and the driver can view the external light reflected by the vehicular electronic rearview mirror 0100 to know the position of the vehicle behind.

With continued reference to fig. 1E, the electronic rearview mirror 0100 for vehicle comprises a first transparent element 0120 and a second transparent element 0130, wherein the first transparent element 0120 faces the driver, and the second transparent element 0130 is disposed at a side far from the driver. Specifically, the first transparent element 0120 and the second transparent element 0130 are transparent substrates, and the material thereof may be glass, for example. However, the material of the first transparent element 0120 and the second transparent element 0130 can also be, for example, plastic, quartz, PET substrate or other applicable materials, wherein the PET substrate has the characteristics of low cost, easy manufacturing, and thinness besides the packaging and protection effects.

In this embodiment, the first transparent element 0120 includes a first light-receiving surface 0122 and a first light-emitting surface 0124, and an external light image from the rear of the driver is incident to the first transparent element 0120 through the first light-receiving surface 0122 and emitted from the first light-emitting surface 0124. The second light-transmitting element 0130 includes a second light-receiving surface 0132 and a second light-emitting surface 0134, the second light-receiving surface 0132 faces the first light-emitting surface 0124, and a gap is formed between the first light-emitting surface 0124 and a sealant 0114. The external light image is emitted from the first light emitting surface 0124 to the second light transmissive element 0130, and then emitted from the second light emitting surface 0134.

An electro-optical medium layer 0140 is disposed in the gap formed by the first light emitting surface 0124 of the first light transmissive element 0120 and the second light receiving surface 0132 of the second light transmissive element 0130. At least one transparent electrode 0150 is disposed between the first transparent element 0120 and the electro-optic medium layer 0140. The electro-optic medium layer 0140 is disposed between the first light transmissive element 0120 and the at least one reflective layer 0190. A transparent conductive layer 0160 is disposed between the first light-transmitting element 0120 and the electro-optic medium layer 0140, and another transparent conductive layer 0160 is disposed between the second light-transmitting element 0130 and the electro-optic medium layer 0140. One electrical connector 0170 is connected to the transparent conductive layer 0160, and the other electrical connector 0170 is connected to the transparent electrode 0150, and the transparent electrode 0150 is electrically connected to the electro-optic dielectric layer 0140 directly or through the other transparent conductive layer 0160, so as to transmit electric energy to the electro-optic dielectric layer 0140 and change the transparency of the electro-optic dielectric layer 0140. When an external light image with brightness exceeding a predetermined value is generated, such as strong head light from a rear vehicle, the glare sensor 0112 electrically connected to the control element 0180 can receive the light energy and convert the light energy into a signal, the control element 0180 can analyze whether the brightness of the external light image exceeds a predetermined brightness, and if the glare is generated, the electric energy is provided to the electro-optic medium layer 0140 through the electric connection element 0170 to generate the anti-glare effect. If the intensity of the external light image is too strong, the glare effect will be caused to affect the sight of the eyes of the driver, thereby endangering the driving safety.

The transparent electrode 0150 and the reflective layer 0190 may cover the surface of the first transparent element 0120 and the surface of the second transparent element 0130, for example, globally, but the present invention is not limited thereto. In this embodiment, the material of the light-transmitting electrode 0150 can be selected from metal oxides, such as: indium tin oxide, indium zinc oxide, aluminum tin oxide, aluminum zinc oxide, indium germanium zinc oxide, other suitable oxides, or stacked layers of at least two of the foregoing. In addition, the reflective layer 0190 may have conductivity, and the reflective layer 0190 may include at least one material selected from a group consisting of silver (Ag), copper (Cu), aluminum (Al), titanium (Ti), chromium (Cr), and molybdenum (Mo), or an alloy thereof, or include silicon dioxide or a transparent conductive material. Alternatively, the transparent electrode 0150 and the reflective layer 0190 may also include other types of materials, and the invention is not limited thereto.

The electro-optic medium layer 0140 may be made of organic materials, or inorganic materials, but the invention is not limited thereto. In this embodiment, the electro-optic medium layer 0140 may be made of electrochromic material (electrochromic material), and is disposed between the first light-transmitting element 0120 and the second light-transmitting element 0130, and between the first light-transmitting element 0120 and the reflective layer 0190. Specifically, the light-transmissive electrode 0150 is disposed between the first light-transmissive element 0120 and the electro-optic dielectric layer 0140 (electrochromic material layer EC), and the reflective layer 0190 of the embodiment may be disposed between the second light-transmissive element 0130 and the electro-optic dielectric layer 0140. In addition, in the embodiment, the electronic rearview mirror 0100 further includes sealant 0114. The sealant 0114 is disposed between the first transparent element 0120 and the second transparent element 0130 and surrounds the electro-optic dielectric layer 0140. The sealant 0114, the first light-transmitting element 0120 and the second light-transmitting element 0130 encapsulate the electro-optic dielectric layer 0140 together.

In this embodiment, the transparent conductive layer 0160 is disposed between the electro-optic medium layer 0140 and the reflective layer 0190. Specifically, the anti-oxidation layer can be used as the anti-oxidation layer of the reflection layer 0190, and the electro-optic medium layer 0140 can be prevented from directly contacting the reflection layer 0190, so that the reflection layer 0190 is prevented from being corroded by organic materials, and the electronic rearview mirror 0100 for the vehicle in this embodiment has a long service life. In addition, the sealant 0114, the transparent electrode 0150 and the transparent conductive layer 0160 jointly encapsulate the electro-optic dielectric layer 0140. In this embodiment, the transparent conductive layer 0160 includes at least one material selected from a group of materials consisting of Indium Tin Oxide (ITO), Indium Zinc Oxide (IZO), aluminum-doped zinc oxide thin film (Al-doped zno), and fluorine-doped tin oxide.

In this embodiment, the electronic rearview mirror 0100 for vehicle can be selectively provided with an electrical connector 0170 such as a wire or a conductive structure connected to the transparent electrode 0150 and the reflective layer 0190 respectively. The transparent electrode 0150 and the reflective layer 0190 may be electrically connected to at least one control element 0180 providing a driving signal by the conductive wires or structures, respectively, to drive the electro-optic medium layer 0140.

When the electro-optic dielectric layer 0140 is enabled, the electro-optic dielectric layer 0140 undergoes an electrochemical redox reaction to change its energy level, thereby exhibiting a dull (dim) state. When the external light passes through the opening of the casing 0110 and reaches the electro-optic medium layer 0140, the external light is absorbed by the electro-optic medium layer 0140 in an extinction state, so that the electronic rearview mirror 0100 for the vehicle is switched to the anti-glare mode. On the other hand, when the electro-optic medium layer 0140 is disabled, the electro-optic medium layer 0140 is in a light transmitting state. At this time, the external light passing through the opening of the casing 0110 passes through the electro-optic medium layer 0140 and is reflected by the reflective layer 0190, so that the electronic rearview mirror 0100 for vehicle is switched to the mirror mode.

In particular, the first light transmitting element 0120 has a first light receiving surface 0122 remote from the second light transmitting element 0130. For example, the external light from the other vehicle behind enters the electronic rearview mirror 0100 through the first light-receiving surface 0122, and the electronic rearview mirror 0100 reflects the external light so that the external light leaves the electronic rearview mirror 0100 through the first light-receiving surface 0122. In addition, the human eyes of the vehicle driver can receive the external light reflected by the electronic rearview mirror 0100 for the vehicle, and further know the position of the other vehicle behind. In addition, the reflective layer 0190 may have optical properties of partially transmitting and partially reflecting by selecting appropriate materials and designing appropriate film thicknesses.

The display of the electronic rearview mirror 0100 for vehicle may be L CD or L ED, and the display may be disposed inside or outside the casing 0110, for example, on a side of the second transparent element 0130 away from the first transparent element 0120, or for example, on a second light emitting surface 0134 of the second transparent element 0130 away from the first transparent element 0120. since the reflective layer 0190 has an optical property of partially penetrating and partially reflecting, the image light emitted from the display may pass through the reflective layer 0190, so that the user can view the internal image displayed on the display to display the warning information.

Besides prompting the driver, the warning information may also be stored in advance in the storage module 0020 for at least one emergency contact information, and when the warning device 0040 generates the warning information, the warning information is sent to the emergency contact information. For example, the warning device 0040 may have a communication module, which can be connected to a telecommunication network or the internet, and send the warning message to an electronic device (e.g., a mobile phone, a computer, etc.) corresponding to the emergency contact information via the communication module. Thereby, the emergency contact is prompted that the physiological status of the driver is not suitable for driving the mobile vehicle 0000.

In the mobile carrier assistance system of the first system embodiment, the physiological status detecting module 0011 can detect the physiological status of the driver and generate a corresponding detecting signal to the warning device 0040, and the warning device generates warning information for subsequent use when receiving the detecting signal indicating that the plurality of physiological statuses of the driver exceed the allowable parameters (i.e., receiving the detecting signal indicating that the physiological status is abnormal).
